Mastering Osmosis Practice Techniques

What is the primary function of the central vacuole in a plant cell?

• To control cell division

• To produce energy through photosynthesis

• To synthesize proteins

• To store water and maintain turgor pressure

In a hypertonic solution, what happens to the water inside a plant cell?

• It remains the same

• It flows into the cell

• It converts into solutes

• It flows out of the cell

What term describes the shrinking of a plant cell due to water loss?

• Endocytosis

• Cytolysis

• Plasmolysis

• Turgor

What type of solution has the same concentration of solutes as the inside of a cell?

• Supersonic

• Isotonic

• Hypotonic

• Hypertonic

Why is it recommended to gargle with salt water when you have a sore throat?

• It cools down the throat

• It provides nutrients to the throat cells

• It creates a hypertonic environment that dehydrates bacteria

• It hydrates the throat cells

What happens to bacteria in your throat when you gargle with salt water?

• They lose water and shrivel

• They gain water and swell

• They multiply faster

• They become isotonic

In a practice problem, if a cell is in a solution with 100% water, what type of solution is it?

• Supersonic

• Hypertonic

• Isotonic

• Hypotonic

Which cell condition will result in the cell gaining mass?

• Isotonic solution

• Supersonic solution

• Hypotonic solution

• Hypertonic solution

What is the water concentration inside a red blood cell with 2% solutes?

• 90%

• 98%

• 2%

• 100%

What happens to a red blood cell in a hypertonic solution?

• It remains the same

• It bursts

• It loses mass and shrivels

• It gains mass
